I doesn't sound too good I'm afraid. Sounds to me like your motherboard may well be causing some problems, some of the symptoms you describe indicate that. Also, if it is the motherboard or the harddrive, the cost to replace and / or repair are going to far outweigh the financial worth of the laptop. What operating system are you running? Do you have the CD? If you cannot access the harddrive or floppy drive and are running 2k or XP you may be able to set the laptop to boot from CD and run a repair or format and re-install. But I am not convinced this will work.
